|Born||April 16, 1497
Suzuo Castle, Aki Province
|Died||July 6, 1571
Yoshida-Kōriyama Castle, Aki Province
Mōri Motonari was born under the name Shōjumaru in a small domain of Aki province in 1497. He is said to have been born at Suzuo Castle, his mother's homeland. His father, Mōri Hiromoto retired as the head of the clan in 1500, and moved to Tajihi-Sarugake Castle along with his son Shōjumaru. As titular head of the clan, Hiromoto was succeeded by his elder son Mōri Okimoto.
History remember the young Mori Shojumaru as a fearless daredevil. It is said he escaped by night with some other kids from the castle of his father, and met lord Amago Tsunehisa and his troops. Shojumaru thought they were the ghosts of the Heike clan samurai, and so tried to become famous with ghost hunt, a kind of practice favoured for the education of the youth of Buke families. And so, Shojumaru came openly to challenge the mounted warrior who looked to him as the general. It was Amago Tsunehisa. The other children were trembling in fear, but not Shojumaru. The young lord shot an arrow toward the veteran lord. Tsunehisa swiftly caught it with his bare hand. Impress by the bravery of his young nemesis, Tsunehisa spared the lads, looking forward to battle against an adult Motonari.
In 1506, Hiromoto died of alcohol abuse. Shōjumaru remained at Sarugake, but was troubled by another clan member of the Inoue family, who was aggressively seizing land.
In 1511, Shōjumaru officially became an adult, or genpuku, and was renamed Motonari.
Succeeding the clan
In 1516, Okimoto died. Okimoto's son Kōmatsumaru succeeded to the leadership of the clan, and Motonari became his overseer. Kōmatsumaru died eight years later in 1523, and Motonari succeeded him.
Battle of Miyajima
In 1551, Sue Harukata revolted against his lord Ōuchi Yoshitaka, forcing him to commit seppuku. Sue installed the next lord of the clan, Ōuchi Yoshinaga, but effectively led the Ōuchi family and its armies, intent on military expansion. In 1554, Mōri, as a vassal of the Ōuchi clan, wanted to avenge the betrayed Yoshitaka, and so he rebelled against Sue, whose territorial ambitions were depleting clan resources. The heavily outnumbered force under Mōri attacked and defeated Sue at the Battle of Oshikibata. Mōri then departed from the mainland to build a fort, known as Miyao Castle, on Miyajima while proclaiming publicly his woe that it would not hold out long against an attack.
Sandwiched between the powerful Amago and Ōuchi clans, Motonari led the clan by carefully balancing actions and diplomacy. Eventually, Motonari succeeded in defeating both and controlled the entire Chūgoku area. In his late years, he crushed the Ōtomo clan of Bungo province.
He had three sons, Mōri Takamoto, Kikkawa Motoharu, and Kobayakawa Takakage, whom he encouraged to work together for the benefit of the Mōri clan. In one instance, he is said to have handed each of his sons an arrow and asked each snap it. After each snapped his arrow, Motonari produced three arrows and asked his sons to snap all three at once. When they were unable to do so (according to a legend still taught today), Motonari explained that one arrow could be broken easily, but three arrows held together could not. It is not known for certain if this actually happened or if it is apocryphal legend.
His eldest son, Mōri Takamoto, while en route to attack the Amago clan, died of a sudden disease, though assassination by poison was suspected. Saddened and angered by his death, Motonari ordered all those responsible to be punished.
- Father: Mōri Hiromoto (died 1506)
- Brother: Mōri Okimoto (1492–1516)
- Wife: Myōkyū, Nomi no Ōkata (concubine)
In all, Motonari had nine sons and two daughters; four children (including Takamoto, Motoharu, and Takakage) were by his wife, three by a consort from the Nomi clan, and four by a consort from the Miyoshi clan.
The parable regarding Motonari, his three sons, and the lesson of the three arrows is believed have been a source of inspiration for Akira Kurosawa when he was writing his epic film Ran. The name of the local J League soccer team, Sanfrecce Hiroshima, was also inspired by this story. "San" means three in Japanese, and "frecce" means arrows in Italian.
In 1997, NHK, the public television broadcasting company of Japan, aired a year-long Taiga drama entitled Mōri Motonari that retold the story of how Motonari rose from the leader of an insignificant military clan to become one of the most powerful warlords of the Sengoku period.
He is represented as a character in both the Sengoku Basara and Samurai Warriors series. He is represented as a character in Pokemon Conquest as the warlord of the Greenleaf Kingdom, with his partner Pokémon being Servine and Serperior.
